resitance is inversly proportional to current when (v) is kept constant
<><><><><>
Because resistance is a function of temperature.
its like a bar graph but with little crosses and you join them up with lines
To determine the value of Stabilizing resistor Rs = Vs/Is = If(Rct +2Rl)/Is Where, Rs = resistance value of the stabilizing resistor Vs = voltage at which the relay will operate Is = current flowing through the stabilizing resitor and the relay If = maximum secondary fault current magnitude Rct = internal resistance of the current transformer Rl = resistance of attached wire leads
The plot of current vs. frequency is not symmetric because the equations for inductive reactance and capacitive reactance are not symmetric. One is linear and the other is inverse.
In the linear region, the transistor has an almost linear I versus V curve, which means that as you increase drain-source voltage, current changes proportionally, e.g. to a loose approximation, the FET behaves like a resistor, whose resistance is set by the gate-source voltage. In the saturation region, the I vs V curve looks like a horizontal line (almost) so it acts like more like a switch (neither of these analogies is exact, but they give the general idea).
Current or "electrical current" (to distinguish it from current in a river) is the flow of electrons in a wire which can perform useful work. The current can be generated by a battery or a generator, or by other means. Current electricity is not a commonly used term. "Current electricity" is the science of electric currents, and it means the same thing as Electrodynamics. Example: the Electrical Sciences can be divided into two parts: Static Electricity or Electrostatics, and Current Electricity or Electrodynamics.
The voltage vs resistance graph shows that there is a direct relationship between voltage and resistance. As resistance increases, the voltage required to maintain the same current also increases. This relationship is depicted by a linear graph where the slope represents the resistance.
To find resistance from a graph of voltage vs. current, you can calculate the slope of the graph. Resistance is equal to the slope, so you can divide the voltage by the current to determine the resistance. The unit of resistance is ohms (Ω).
In the graph of voltage vs current, the relationship between voltage and current is linear. This means that as voltage increases, current also increases proportionally.
The current vs voltage graph shows that there is a linear relationship between current and voltage in the given circuit. This means that as voltage increases, the current also increases proportionally.
The relationship between the voltage and resistance in a filament lamp is non-linear. As the voltage increases, the resistance in the filament of the lamp also increases due to the heating effect. This increase in resistance causes the current to increase at a slower rate than expected, leading to a non-linear slope in the voltage-resistance graph.
The slope of a graph of potential difference vs current represents the resistance of the component or circuit being analyzed. It is calculated using Ohm's Law: V = IR, where V is the potential difference, I is the current, and R is the resistance. A steeper slope indicates a higher resistance, while a shallower slope indicates a lower resistance.
The voltage vs current graph represents the relationship between voltage (V) and current (I) in a circuit. It shows how the current flowing through a circuit changes in response to changes in voltage. By analyzing this graph, one can determine the resistance of the circuit, as resistance is equal to the slope of the graph (R V/I). This can help in understanding how voltage and current interact in a circuit and how different components affect the flow of electricity.
The slope of a voltage vs. current graph represents the resistance in the circuit. It indicates how the voltage changes with respect to the current flowing through the circuit. A steeper slope indicates higher resistance, while a shallower slope indicates lower resistance.
voltage= f(ln(r)) graph is linear and voltage vs distance is non linear because voltage changes with 1/r so the graph is with curve. we use ln because ln direct the graph.
The resistance vs length graph shows that there is a direct relationship between resistance and length. As the length of the material increases, the resistance also increases.
The easiest circuit that does not obey Ohm's law is a circuit that has a resistance that depends on temperature. For example, if you take a light bulb and draw a current-vs-voltage, you see that in the beginning (under low voltage) the graph is NOT a straight line, but under high voltage the graph is linear. This is because the resistance depends on temperature. the equation V=IR isn't consistent with the graph's shape.
The resistance vs temperature graph shows how the resistance of the material changes as the temperature increases. It helps to understand the material's behavior in response to temperature changes.
